Another Irish Joke

This one is from a friend of ours, Mike Molloy:

'Hi,Can I have some Irish Sausages, please?' asked the Irishman, walking up to the counter.
The assistant looked at him and asked: 'Are you Irish?'
'If I had asked you for Italian sausage, would you ask me if I was Italian?' demanded the Irishman indignantly.
'Or, if I asked for German Bratwurst, would you ask me if I was German?'
Then, warming to his theme, he went on: 'Or if I asked you for a kosher hot dog, would you ask me if I was Jewish?'
'Or, if I asked you for a taco, would you ask me if I was Mexican? Would ya? Would ya?'
The assistant said: 'Well, no.'
Suitably encouraged by the success of his logic, the Irishman steps it up a gear.
'And if I asked you for frog’s legs, would you ask me if I was French?'
'What about Danish Bacon, would you ask me if I was Danish?'
'Well no, I probably wouldn't' conceded the assistant.
So, now bursting with righteous indignation, the Irishman says, 'Well, all right then, why did you ask me if I'm Irish just because I asked for Irish sausages?'
The assistant replied, 'Because you're in Home Depot.'
